The “hiperfile concept” encompasses numerous system software and hardware enhancements in BS2000 that are designed to accelerate file access and prevent a possible I/O bottleneck by “caching” files. High-speed semiconductor memory with short access times is used as a buffer (or cache) that enables adjustments to be made between the time required to access main memory and the (slower) access to external hard disks.
The HIPERFILE concept in BS2000 provides with the so called ADM-PFA (Administrator Performant File Access) caching within the main memory via privileged commands of the software DAB.
ADM-PFA caching designates the use of the concepts, methods and commands of the DAB cache handling system (START-DAB-CACHING). ADM-PFA caching is described in the “DAB” manual [5 (Related publications)].
